We welcomed back Bob Zimmerman to discuss current and hot topics happening in space at this time.  During the first segment of our 2 hour 6 minute discussion, Bob asked me about the recent Bay Area-NAPA earthquake on Sunday morning, August 24, then we switched over to space topics starting with SpaceX and the Falcon 9R test launch explosion.  Next, Bob talked about the failure of the ESA Galileo GPS launch involving the Soyuz-Arianne.  Several questions came up regarding the ESA GPS system. We also talked about other regional GPS systems.  Bob moved us to the launch failure (booster rocket) for the Air Force Hypersonic vehicle, then to the decision by Sea Launch to take a break.  Bob had much to say about the Sea Launch partnership now involving mostly Russia and the Ukraine.  Russia and the ISS came up and here Bob also had much to say, including going over the news that Russia may now be interested in extending the life of the ISS.  Bob suggested some important Russian reasons for wanting to do this, see what you think.  The Atlas RD-180 rocket engine came up for discussion as did the upcoming NASA down select for commercial crew with Dream Chaser, SpaceX, and Boeing with their CST 100.  Next up was SLS which I permitted to be discussed for a while, including a call by SLS John in Ft. Worth, then I stopped it and said that SLS was a beaten to death topic on the show and that listeners and I were sick of it.  I said no more SLS talk unless there was something new on one side or the other of the SLS issue.  At one point I even assigned SLS John a new topic to research and call in about.  Let us know with your blog comments, are you sick of SLS discussions on TSS? Do you want to keep hearing them or not?  Luis emailed in about having GPS redundancy and backup systems re the European system as an example. Bob had specific ideas about this but thought the better route would be to be able to quickly replace a lost or destroyed satellite.  As the segment neared its end, Joe asked about CST and Falcon 9/Heavy & Bob had more to say about ISS modules & Doug asked a series of questions about the benefits of extending ISS to 2028.  Don’t miss Bob’s response.

In the second segment, Joe asked about small sats taking over market share from the previous big satellites.  Bob provided an interesting short discussion on this topic.  SLS John called back about the Falcon Heavy flying and then somehow the discussion focused in on presidential candidates and their space policy in upcoming elections.  After a short non-partisan review of what Bob thought might unfold depending on which party wins in November, we moved on to Rosetta and 67 P.  Bob talked about the lander and the landing sites.  Tim called in to talk about a proposal announced for space debris tracking with Lockheed and Electro Optic Systems in Australia (see http://www.lockheedmartin.com/us/news/press-releases/2014/august/0825-ss-electro.html).  Also discussed was nuclear propulsion, the Space Fence, then we got emails about fusion energy progress.  Near the end of the program, Bob talked about Curiosity, some of the electrical issues with using the on board drill, and of course the tire problem.  As the show was about to end, Kirk emailed about the recent Chinese ASAT test and Bob suggested we look for an end of the year Dragon abort test, another Falcon 9 flight and more flight tests, and the Rosetta landing on 67 P scheduled for November.

We welcomes Randa and Rod Milliron back for this 1 hour 36 minute discussion about their company, Interorbital Systems (IOS), rocket engine development and testing, and much more.  Visit their website at www.interorbital.com for more information and details of topics discussed today.  We started out by getting details about the IOS static engine test in Oct. 2012.  Our guests talked about the test and described their engine and the Neptune modular launch system.  Rod talked about using hypergolic propellants and why they chose to do so, plus our guests went over the capability of the Neptune rocket depending on how many modules and stages were used.  They also talked about adding a stage for the lunar lander as they are a GLXP participant.  We talked about the GLXP, getting secondary payload rides to the Moon or using a dedicated launcher such as the Neptune. Our guests described their plans for doing a sea launch and why, probably in the Pacific Ocean near Hawaii.  They also talked about having spaceport launching capabilities as well.  Listeners asked about demo flights and time lines, plus suborbital test flights.  Another listener asked about the plans for Olav Zipser to jump from a rocket in light of the Red Bull success.  Wes from Tampa emailed in about suborbital flights offering a space view for sensor testing, retrieving payloads, & testing low gravity manufacturing/3D printing.  IOS suborbital flights are their test flights.  Our guests had much to say about these matters, especially retrievable payloads.  Blair emailed in about IOS due diligence, their launch track record, and their consumer sales.  We then talked about the IOS personal satellite TubeSat and CubeSat kits. Wes called in to talk about his positive experiences given he has purchased one of the kits.  I also asked Wes about his due diligence on IOS before buying the kit.  Listen to how our guests and Wes responded to this line of questioning.

In the second segment, I asked about engine test regulations & required permits for testing at Mojave.  Randa and Rod mentioned complying with ITAR because they have foreign sales of the personal satellite kits.  They also talked about a 4H group on the Utah Colorado border building a personal satellite and the educational outreach this involves with the Ute Native Americans and others.  The Millirons were asked about their being considered fringe by some in the space community.  Note what they said about this and about attending space conferences.  A question came in as to why they were not using a hybrid engine.  Rod had lots to say about hybrids, don’t miss his comments.  Our discussion concluded with a summary of their forthcoming rocket plans and development program.

Contact Dr. Livingston for questions about our copyright & trademark policies.  We welcomed back Paul Breed of Unreasonable Rockets to discuss space business plans, low cost space access, NewSpace outcomes to date, & his nanosat launcher business concept.  In our first segment of this two hour discussion, Paul started out by presenting us with an overview of space access & NewSpace vehicle development starting with the Shuttle through today.  We talked about both orbital & suborbital launches & his comparing the suborbital industry with the orbital launch industry.  He made a very good case for his comparison but see what you think after hearing our discussion.  Paul summarized & discussed the vehicles under development & then he gave us an overview of his nanosat launcher concept.  He told us that we could download & read his business plan & more at his blog, www.unreasonablerocket.blogspot.com.  He has three documents on his blog for your download & review.  In our discussion, Paul outlined his financial performance characteristics for his concept & responded to listener questions about it.  Charles called in to support Paul’s concept & to plug his Microlaunchers concept.  I brought in Dr. John Jurist on another line who joined in talking about the business plan Paul made available on his blog.  Some of the issues talked about were one man business operations as opposed to a company with staff, engineers, etc. key man insurance, venture capital considerations, company infrastructure, & funding levels.  We also talked about what makes an effective business plan.  John & Paul then entered a discussion about nanosat launcher first stages as opposed to needing a two or three stage rocket.
    In the second segment, the issue of venture capital flowing to hardware as opposed to software came up for discussion.  I referred to earlier programs plus a lecture we had at the NewSpace meeting about the flow going to software now, not hardware.  Paul continued on with some of the technical concepts for his nanosat launcher concept, we talked about the three components of cost plus market timing, financial interest in such a plan, & the fact that the nanosat launcher market is undergoing exponential growth.  Paul also talked about “hitchhiking” secondary payload rides, academic launches for cubesats & the market for the launches, & the interest in nanosat launchers outside the U.S., especially the entrepreneurial interest in such a business.  Paul talked about the fact that NASA has set very high expectations, that Hollywood movies have done the same & that such contributions to the industry are & have been destructive.  Don’t miss this discussion.  We talked about some of the newer technologies available today including 3D printing & crowd source financing as examples.  In concluding our discussion, Paul asked for listener feedback on his business plan & concept as well as for ideas using Kickstarter as a possible source of financing.
     Please post your comments/questions on The Space Show blog per above.  Paul can be reached directly through is own blog.

Dr. Jordin Kare, Sunday, 5-20-12

http://archived.thespaceshow.com/shows/1778-BWB-2012-05-20.mp3

Guest:  Dr. Jordin Kare. Topics:  Beamed energy propulsion updates.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, https://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. We welcomed Dr. Jordin Kare back to the program for beamed energy propulsion (BEP) industry updates.  Be sure to visit his website for more information, www.lasermotive.com.  Our discussion started out by referencing two recent BEP studies involving NASA. The first, the Beamed Energy Propulsion Study was completed last year and was a joint study with DARPA.  The newer study which is still being finalized is the NASA Ride The Light Project.  As you will hear, these studies suggest technical feasibility but call into question basic economic questions such as is BEP worth it and who will pay for it.  Dr. Kare and I then engaged in an interesting discussion about the NASA cost estimation compared to Dr. Kare’s cost estimation.  I urge you to listen carefully to this discussion.  You may find as I and others did that it explains a lot regarding economic challenges to our current space programs. A listener as Jordin about the costs for a laser demo project.  Jordin then estimated costs depending on the type of demo project involved.  Also, Jordin was quick to point out that the economic conclusions of the studies were not the kiss of death as I suggested so again, listen attentively to what he has to say about this matter.  Ben emails us wanting to know how laser beamed energy works.  Jordin then described the basics of BEP, requirements for the beam to always be hitting the rocket all the way to space, and many factors related to laser launch.  We talked about the hydrogen fuel, the need to be in a cloud free location, and the theoretical limits to a BEP system.  Basic ISP was discussed and Jordin compared to BEP to traditional chemical rockets and different fuels.  BEP is about twice the ISP of a typical chemical rocket.  Dr. Kare described the three schools of thought and approaches to BEP, and as the segment ended, he responded to a question about the space elevator concept.

In our second segment,Alice asked about the ease in getting federal grant money for BEP projects and we learned its not easy.  A listener asked for a basic explanation of power beaming so Jordin took us through the power beaming and wireless power transmission concepts.  We talked about near term commercial projects using lasers and here, Jordin directed us to his company, LaserMotive, as they are involved in several commercial projects unrelated to space.  This is another interesting discussion, don’t miss it.  A caller asked how the laser beam is kept aligned with the rocket as it accelerates to orbit.  He also asked about problems resulting from the wobble.  I asked about laser launch for HSF, launch abort issues, and a listener asked about the laser frequencies used.  Other subjects included the military use of lasers, migratory birds, & thin film solar panels. As our program ended, Jordin was asked look at laser launch over the near and intermediate term plus if it could be used for sea launch.
